Find the prime factorizations of your age and the other two persons’ ages. Show your work listed by name and age. Make sure your work is clear and concise.

Find the LCM and the GCF for each set of numbers. Again, be clear and concise. Explain or show how you arrived at your answers.

In your own words, explain the meaning of your calculated LCM and GCF for the ages you selected. Do not explain how you got the numbers; rather explain the meaning of the numbers. Be specific to your numbers; do not give generic definitions.

Respond to at least two of your classmates’ postings. Did your classmates calculate the LCM and GCF correctly? Are their interpretations correctly applied to the ages?

GCF <= 40.

1 * 70 = 70

2 * 35 = 70

5 * 14 = 70

7 * 10 = 70

1 * 55 = 55

5 * 11 = 55

1 * 40 = 40

2 * 20 = 40

4 * 10 = 40

5 * 8 = 40

GCF = 5.

LCM =>70

Limit max. value to:70*55*40= 154000.

These numbers are very hard to work

with. I did this mostly by trial and error:

2 * 70 = 140

3 * 70 = 210

30 * 70 = 2100

40 * 70 = 2800

44 * 70 = 3080. This # is divisible

by 70, 55, and 40. It is the smallest

i could find.

LCM = 3080.
